I understand having a bad week. I have been having one myself between not recording food, and having a friend down for a couple of days which translated into unbridled food consumption, including ice cream on both days - absolutely evil for me as it is my weakness. To counteract, I have eaten healthy yesterday and today, and finally wrote my food out tonight.
Have you done anything the last couple of days to get back on track in regards to your eating or food journaling? And yes, you can show some bulk when weight lifting. However, it is good fit muscle which looks far better than skinnier flobbly bits. My thighs are pretty solid thus skinny leg jeans look silly on me. I just buy a boot cut, a straight leg, or a boyfriend cut jean style instead to accommodate my thighs. And just think...if your thighs are firming up, that means your butt is perking up too! All the better to fill out the backside of your jeans!
